Women wanting breast implants after cancer surgery or
women who want to augment their breasts may be able before long to have
living tissue grown from their own cells implanted instead of silicone,
Britain's Sunday Times newspaper reported.
American scientists have already succeeded in growing nipples and
associated tissue using human cartilage cells, the newspaper said.
Tissue engineers at the U.S. company Reprogenesis expect to try
transplanting the nipples onto patients next year and predict that in five
years time they will be able to create whole breast transplants, it said.
The development could revolutionize treatment for women who lose
breasts through cancer by offering a safer alternative to silicone
implants. The breasts may also be available for cosmetic purposes, the
Sunday Times said.
The nipples are grown from a small sample of fat and blood vessel
cells taken from the buttock or thigh.
These are seeded onto a pre-shaped scaffolding of polymer plastic and
growth factors added to promote cell division. The cell growth slows when
the scaffolding is full and the polymer disappears leaving natural tissue.
Because the breast is created using the patient's own cells, there is no
risk of the body rejecting it, the newspaper said.
